RB Woodward

In his Cope Lecture, Woodward said it best when he acknowledged the special
challenge of chemistry compared to mathematics:
“While in mathematics, presumably one's imagination may run riot without
limit, in chemistry, one's ideas, however beautiful, logical, elegant,
imaginative they may be in their own right, are simply without value unless
they are actually applicable to the one physical environment we have- in
short, they are only good if they work! I personally very much enjoy the very
special challenge which this physical restraint on fantasy presents.”
“In chemistry, ideas have to answer to reality”
